Security

3M fragment retention window films increase the security of window openings from bomb blasts, seismic events, windstorms, and forced entry by helping to hold glass in place.

Fragment retention film was credited for saving many lives in the September 2001 terrorist attack on the Pentagon. When an explosion occurs, nearby glass may implode into tiny sharp fragments and subject building occupants to a high level of danger.

In addition to nearby explosions, fragment retention film is used to protect building occupants from earthquakes, other seismic events, hurricanes, and smash and grab crime.

These films are manufactured of multiple-layers of tough, transparent polyester. This nearly invisible protection has been around for many years, but has only recently gained wide acceptance in the United States - primarily because of the Oklahoma City bombing and the September 11th terrorist attacks.

Testing has shown that fragment retention films hold glass in place during an explosion. 3M fragment retention films meet or exceed federal government standards when tested to the GSA/DOD/USACE Security Criteria.

3M fragment retention films are maintenance-free and are warranted by the 3M Company to maintain their optical clarity without any peeling, cracking, or discoloration.
